Weekend Plans: Zombies, Air Sex And More

As usual, Chicago comes through with another weekend of wacky activities. Whether you want to act like a zombie, save the world or have fake "relations" in front of hundreds of strangers, there's something for everyone going on this weekend in the Windy City.

Critical Mass Bike Ride: Meet up at Daley Plaza for this monthly bike ride that floods the streets of downtown Chicago with cycles. Though it originally formed as a way to make a statement about transportation, Critical Mass has become a way for cyclists all over the city to simply enjoy biking together (while also running a few red lights).

118 N. Clark St.

Chizakaya's Prix Fixe Spring Menu: This Saturday is the last chance you'll have to get the special prix fixe spring menu at popular Lakeview eatery Chizakaya. Enjoy inventive Japanese dishes like chicken donburi, crab-crusted salmon and sesame fried mochi. Don't forget to add on sake pairings for $25 each.

Zombie Pub Crawl: Playing dead isn't just for dogs anymore. Put on your best zombie makeup and head to Andersonville's fourth annual Zombie Pub Crawl. Instead of human flesh, you'll get to hunt for "beer-rains" at some of the neighborhoods hottest bars, like Atmosphere, The Call and Farragut's.
